Hi,
Can you help me, 1. When I'm using NicheStack(DM9000A as NIC),I met some strange problems: when i'm debugging TCP prot,the program entered ip_output() function.It triggered a panic(),and told me this message: ip_output: overflow The program crashed after this message... How to avoid this ? 2. The bit[0] of DM9000A's TX Control Register (TCR) sometimes don't clear itself after sending completely. I wrote: while(ior(TCR)&0x01) { udelay(5); } and the program stuck here.... What should I do? Thank youLink Copied
